Start with the triggers

"Why don't we give each girl individual triggers," said Ren. "And universal ones?"

"So Sis will have her own batch of triggers, as well as a trigger she shares with Ann and Futaba?" asked Makoto.

Ren nodded. "Yep. And if we want the specific girl to act out a group trigger but not the rest, we just do what we did with the freeze trigger and make it activate with their name."

"Okay," said Makoto. "I have an idea then."

She faced the girls. "Okay you three, if we ever say the word...pineapple...you will orgasm then forget you orgasmed."

"Pineapple?" Ren asked.

Makoto shrugged. "It's not a common enough word to come up in casual conversation."

"Fair enough," said Ren. "To add on to that, if we ever say pineapple followed by a number, you'll orgasm that amount of times. So if we say 'pineapple five', you'll orgasm five times."

"Also," Makoto continued. "If we say your name followed by pineapple, only that person will orgasm. So if we say 'Ann pineapple four', Ann will orgasm four times, but Futaba and Sis won't."

"Excellent start," said Ren. "Want to give them their individual triggers now, or do you have an idea for another group trigger?"

"We should probably add the freeze trigger to Sis," said Makoto.

"Right," said Ren. "We can do that later."
